Hi guys - I am an old school diesel injection guy originally from UK now living in New Zealand. I am trying to help an old tractor enthusiast friend of mine ( he has no Internet) with a problem. This is it in a nutshell.
We have a 1960’s International 606 Tractor with a D236 engine.
It idles perfectly at 600-650 rpm. When the throttle is opened there is a knocking sound (similar to “diesel knock”) for about 2 to 3 seconds then by the time the engine has reached 1000rpm the noise completely disappears and the engine runs beautifully at all speeds. I haven’t actually heard it myself but the owner says he thinks he can hear the noise through the inlet manifold. We are pretty certain the noise is not caused by the injector nozzles as they are all new plus there is no smoke of any sort when the knock occurs. The owner says it is just annoying really rather than being a major problem but he would like to get to the bottom of it – and so would I !! There is a possibility that the guy who re-worked the cylinder head has used brass or bronze valve guides – could this be anything to do with it do you think?
